Hi,

Caputring mouse position is discussed here.

It's possible to provide libraries per technology, so basically you can specialize a PCell for a technology: implement a generic base class in a general module, then derive a class for a given technol

In general, I am interested for the PCell development and I am trying to use the idea of this example as a base: https://www.klayout.de/forum/discussion/comment/4444#Comment_4444. I am trying to build

just one. The corresponding method is Netlist#combine_devices.

The marker browser is exactly build for this purpose. If you're able to format the list of coordinates in it's XML format, you're done. It's also possible to fill a marker database using a script and

An example for "copy_tree" can be found here: https://www.klayout.de/forum/discussion/comment/2279#Comment_2279 in the final post of mine.

For the step-by-step question there is a related discussion already: https://www.klayout.de/forum/discussion/comment/4888#Comment_4888

The first method works with "Cell#copy_tree". The second version can be done even with a DRC script. Here is a rough sketch (not tested):

#compare two method to calculate the density mapimport pyaimport timepixel = 9pattern_layer = 1000gds_file = "C:/Users/Aeolus/Desktop/testcase1.gds"layout = pya.Layout.new()layout.re

So maybe it would be good to have a "safe merge" hard coded in C++ since Python name compares are probably slower than C++. It looks like "cell#copy_tree" implement

There is no method for "Import layout from another file", because this feature is just using "Cell#copy_tree" or "Cell#copy_tree_shapes":

If you need better control, you two layout objects and Cell#copy_tree to copy over the cell trees from the new layout object to your working object.

The safe way I advise in general is to use "Cell#copy_tree" which takes care of creating unique cells. In your case the script using "Cell#copy_tree" looks like thi
